TUBE PASTE DISPENSER AND VALVE CLOSURE THEREFOR Filed July 7, 1935 INYENTQR- fZzb%ard/fz%mas; Q BY MW ATTQRNEY- Patented Oct. 30, 1934 PATENT OFFICE TUBE PASTE DISPENSER AND VALVE CLOSURE THEREFOR Richard Kirmss, Brooklyn, N. Y.

Application July 7, 1933, Serial No. 679,278

6 Claims.

The present invention relates to a holder for dispensing tooth or other paste from a supported collapsible tube of the usual type.

The present device is intended to be attached to the wall of a room, and to be manually operated to discharge a little of the paste from the discharge end of the tube, as required, and to support the tube until emptied, in operative paste discharge position.

, Another object is the provision of a quick acting tubesealing valve for the discharge end of the tube, whereby the said end may be provided with a separate, manipulable, quick opening and closing sealing means as a substitute for the usual cap which is discarded, and, thereafter the separate sealing means is left on the tube until it is emptied. Further, the said separate tube sealing means may be used apart from the herein shown tube discharging support, and is provided with means so that the tube, when not in use may be hung on a wall hook, if desired.

The present wall tube holder and separate tube sealer are provided with means whereby they mutually coact to combine, in assembly, a complete tube paste dispenser. as will hereinafter be noted.

These and other capabilities will be apprehended as the herein description proceeds and it will be noted that modifications may be made in the structure herein without departing from the spirit hereof, or the scope of the appended claims.

In the drawing,

Fig. l is a front view in elevation of the present device;

Fig. 2 is a side view thereof showing the paste tube in dotted lines, as supported;

Fig. 3 is a bottom view, looking upward, of Fig.1;

Fig. 4 is a side view of the spring clip seat with its support broken away; and

Fig. 5 is a central sectional view of the tube sealing valve.

The present device comprises a wall affixing base plate 1, having means, not shown for aflixing to a wall in any known manner, and being provided at its lower end with an outstanding support lug 2, this lug having a flange 22 thereon and as in Fig. 3, a lug 3, shown dotted, whereby 50' the flanged lug 2 may be riveted to the base plate.

At a thickened portion of the lug 2, is mounted an upright rectangular slide post 4, which is riveted, by a neck portion 5, shown dotted in Figs. 2 and 3 to the lug 2, in an upright position and parallel to the base plate 1. The outer end of the lug 2 has a thickened clip end 21, arranged to suitably hold and seat therein a semicircular spring clip 20, Figs. 3 and 4.

The slide post 4 mounts thereon a slidable paste tube compressing means, comprising a rectangular bearing tube 7 slidably fitted to upright 4, and upon which tube is mounted a U-shaped yoke 6, which has angled arms having bearings 99 thereon, which bearings are parallel to and spaced a distance away from one another.

In the bearings'8--8 is rotatably mounted a slotted tube-end compressing means 10, having a long slot 11 therein, and has two bearing ends 99 rotatably supported in bearings 8-8. One bearing 9, comprises a threaded shank 13, which is threadedly connected to the compressor 11. The outer extension of this threaded shank bearing 913 has an integral extension 15 upon which is located a knurled thumb-nut 12.

With the rear fiat end or closure A of the paste tube inserted in slot 11, the knurled nut 12 is rotated and this winds the paste tube upon compressor 10, and causes the paste within the tube to be placed under pressure, as indicated by the dotted lines 'I' in Fig. 2.

The lower threaded tubular discharge neck or end of the tube, shown in dotted lines, Figs. 1 and 2, is provided with a threaded on sealing valve generally denoted by 16. The cap in this instance is discarded, the valve 16 removed from the support lug 2, and the valve screwed on the discharge end of the tube T.

Thereafter the valve 16 is snapped into the clasp of the spring clip 20, the rear flat end of the tube inserted into the slot 11 of compressor 10, and the tube is ready for use, as in Figs. 1 and 2, when the valve head 31 is swung oil from its ported seat or head 27.

To understand this, reference is had to Fig. 5 in which the tube sealing valve structure is shown in section, and as comprising a body having a port clean through its center, opening at one end 1'7 into a threaded bore 18, which receives the threaded end of a paste tube, and at its other end opens into a rounded discharge end 27.

The valve head end 17 is provided with a circular groove 19 therein, thus forming two opposed flanges 33-33, the peripheral faces of which may be knurled. The groove 19 forms a seat into which the spring clasp 20 may enter, to hold the threaded tube in firm operative position when the assembly is accomplished as in Fig. 2.

The head end 17 of the valve is provided with a circular head 27, having a flange around the tubular portion 23 and resting against the ledge or flange 24 of head 27 is a coiled compression spring 26, the opposite end of which supports a loose, movable collar 28. The collar 28 is thus normally stressed, to be pressed against the lower face of the. lower knurled ring. 33, when the valve 31 is snapped off of its seat port 27 as in Figs. 1 and 2.

The collar 28, has two holes bored in its perimeter, at opposite sides thereof as in Fig. 5,

and into these holes are inserted the two bent, angled ends of a U-shaped' bail; on wire" clip, the outer end of which clip is formed. giving; the Wire a double coil 30. Mounted. on the op.- posing legs of the wire clip is a valve seat member, comprising a flanged portion 31", through. which the wire legs 29-29 pass to support said valve, and a semi-spherical seat 32 is carried by said flange, so that when the valve seat 32 is in operative position on the paste tube port 25, said valve is firmly held tov said seat to close the port 25,. and is easily snapped aside, as in Fig. l, to uncover said port, to permit paste to issue therefrom. Thereafter the valve may be snapped back on its seat as in Fig. 5. I

In" use; the valve 32 is pushed aside and the knurled nut 12" is turned, thus causing the do sired amount of paste to be discharged fromport 25; the delivered paste is then removed and the valve 32 replaced, as" previously described.

When the tube is completelycollapsed and empty; the valve 16 is released from its spring seat 20; the tube compressor 6- i'sslid off of post 4, upwardly; the collapsed tube removed, a new 5 the valve 1-6 alone, as while traveling, without the Wall plate, and in this instance, the paste tube cap is discarded, the valve 16 substituted as before; and thus thetube is provided with a non-losable cap; quickly opened or closed, but" neteasiIy accidentally opened.
